在65℃的开放体系中，用低温水化学方法成功地合成了直径50~200 nm、长度100~800 nm的Bi2Te3中空结构纳米胶囊。管壁厚度约为6 nm，法向平行于Bi2Te3晶格的c轴。对合成过程中的化学反应和纳米胶囊的形成进行了原位研究。
Bi2Te3 nanocapsules with hollow structure have been successfully synthesized by a low temperature aqueous chemical route in an open system at 65 °C. The nanocapsules are 50–200 nm in diameter and 100–800 nm in length. The tube walls have a thickness of about 6 nm with the normal parallel to the c-axis of the Bi2Te3 crystal lattice. Chemical reactions during synthesis and the formation of the nanocapsules were investigated in-situ.
